Engine bogs down/stalls when pumping brakes

So, as the title suggests, the engine hops about 300 rmp when I pump the brakes. While doing this to try and diagnose it, one of my brake lines burst (go figure :th_sick1:). So I just replaced the brake line, bled the system as best I can (the bleeder is not coming loose, and I'm scared the bolt will break). But, while testing the brakes after bleeding them, the car gets bogged down and stalls.

I've done a quick look at the vacuum lines to the brake booster. Any other thoughts?
 


your vac booster may be going, but that usually results in a hard pedal.

id think vac leak, spray some soapy water around the brake booster and vac hose, the rubber seal all that good stuff.
